Research on Discrete Element Numerical Simulation of Orebody Mining in Jiangfeng Iron Mine
In the process of ore body mining,it is an important research work to determine the impact of different mining plans and depths on the upper surrounding rock,surrounding rock and surface.Therefore,the discrete element software is used to analyze the mining conditions of the caving method in the Ⅱ ore block of Jiangfeng Iron Mine.The caving phenomenon of hanging wall rock at different mining depths and the impact on surrounding rock strata are studied by numercial simulation.The results show that the discrete element numerical simulation method is feasible and conforms to the basic laws of Rock mechanics.Under the open field conditions,the mining of Ⅱ ore block will lead to large-scale caving of upper wall rock.
